My invention relates to improvements in tooth brushes, and it consistsin the combinations, constructions4 and arrangements hereinafterdescribed and claimed.

5 An object of my invention-Yis to provide a tooth brush which isprovided with means for removing larger particles of foreign matter fromthe teeth and at the same time acting as a polisher for the teeth, thismeans 'lo working in combination with the usual bristles. The co-actionbetween the bristles and the auxiliary cleaning and polishing member issuch as to leave the mouth in a more healthy condition than is possiblewith the standard tooth brush.

A further object of my invention is to provide a device of th'e typedescribed which is extremely simple in construction andA which isdurable and efficient for the purpose intended.

Other objects and advantages will appear as the specification proceeds,and the novel features will be particularly pointed out in theappendedclaim.

My invention is illustrated in the accompanying drawing, in which Iigurel is a top plan View of the device, an

Figure 2 is a section along the line 2-2 of Flgure 1.

In carrying out my invention, I provide a tooth brush that has a handleortion 1 and a bristle-carrying head 2. 'Iu ts of bristles 3 are set inthe head 2.

from the handle 1, I dispose a tooth cleaning and polishing member 4.VThis member has a pointed end 5 that may be used for cleaning betweenthe teeth and also for polishing the surfaces of the teeth. I have foundthat a comparatively soft rubber is the best material to use for themember 4.

The member is provided with a reduced shank 6 that fits in an opening 7in the head 2. The member may be removed from the head and a new onesubstituted.

From the foregoing description of the various parts of the device' theoperation thereof ma be readily understood.

The toot v brush is used in'much the same At the end of the headfurthest removed I 1929. Serial No. 357,298.

manner as a standard one. The brush head 2 is placed Withinthe mouthwith the bristles 3 and the member 4 contacting with the teeth, and thenthe handle is moved for imparting a vertical reciprocal movement to thebrush head in the mouth. The pointed end 5 may be moved between theteeth andA will dislodge the larger pieces of foreign matter. The member4 also acts as a polishing member Iand causes the teeth to glisten andto appear whiter than is possible with a 'standard tooth brush employingonly bristles. n

In use, the member 4 will, `during the manipulation of the brush, tendto traverse the gum line or gingivae and will, as a consequence whereof,be extremely effective 1n dislodging calco-globulin deposits from aboutthe gingivae and the spaces between the teeth in addition toaccumulations of other foreign matter finding lodgment in the saidspaces and about the base of the teeth.

The entire mouth may be gone over with this'brush and the result will bea perfectly 7 clean and healthy condition of the teeth. v

Although I have shown and described one embodiment of myfinvention, itis to be understood that the Same is susceptible of various changes, andI reserve the right to employ such changes as may come within the scopeof the invention as claimed.

I claim:
